摘　　要：随着矿产资源开采逐步向深部发展,将面临着高地应力的问题,探索高应力环境下的采场结构是大规模高效开采的关键。以思山岭铁矿为研究对象,本文将开展大直径深孔空场嗣后充填法采场结构研究,对传统条形采场和方形采场进行模拟分析。研究表明,采用方形采场布置比条形采场布置,更有利于应力分布,有利于工程稳定,故推荐思山岭铁矿深井开采采用40 m×40 m的方形采场,同时为同类深井厚大矿山大规模开采提供借鉴意义。As the mining of mineral resources gradually goes deep, the problem of high geostress will be encountered. The exploration of stope structure under high stress environment is the key to large-scale and high-efficiency mining. With Sishanling Iron Ore Mine as the research object, this paper will carry out the research on the stope structure of large-diameter deep-hole open stope with subsequent filling, simulate and analyze the traditional strip stope and square stope. The research shows that square stope layout is more favorable to stress distribution and engineering stability than strip stope layout. Therefore, it is recommended that the Sishanling Iron Ore Mine adopt 40 m × 40 m square stope for deep shaft mining, which can also provide reference for large-scale mining of the similar deep and thick mines.
